Installing Metal Siding



You’ve decided to install metal siding on your steel building, and now have realised how difficult it can be. Well, it’s true. Metal siding is a more difficult product to install if not installed by a professional.  Most builders will recommend vinyl or aluminum siding for building owners who would like to do it themselves.  These materials are light weight making them easier to install.  Below are some tips on how to install metal siding properly.

Before installing metal siding, be sure to measure the height and width of the walls first. This should include gable ends, dormer sides and gambrel walls and subtracting the square footage of the garage doors and glass or sliding doors.  Add the total net square feet by 100.  Next, you need to prepare the surface of the building before any other construction takes place. Make sure to hammer any loose nails or replace any rotted wood. This also includes removing any old paint, old putty and/or caulking.  And remove all gutter downspouts and tie back plants.  Next, you must attach aluminum foil underlayment as an insulator for siding and staple it to the walls. When selecting underlay, go with a perforated or breather type which allow for passage of water vapors.   All openings must have underlayment especially by the edges and in all corners. The underlayment must overlap by 2 inches at all sides.  

For a better reference line for your starter strip, snap a chalk line from one end of the building to the other. Be sure that the lines are straight when hanging up your steel siding.  Don’t forget to also measure the eaves, under windows and down to the bottom of the building to allow for perfectly hung parallel siding to the soffits. After you have completed this section, drive a nail into the centre of the predrilled hole in order to allow for a snug nail.  Then the siding will hang off the nails, not hammered in.  Keep in mind that over time, steel siding does change shape and colour especially with weather conditions and be sure to not nail the siding too tight.  When selecting nails for the steel siding to be hung, a good choice would be 2-inch galvanized steel nails.  Be sure to hammer the nail in straight and not on an angle to prevent the siding from tilting. Be sure to space the nails about 16 inches to where the studs are centered.  

When installing the starter strip, be sure to follow the chalk line you created earlier all the way around the building.  Make sure to use a level to make sure the starter strip is straight.  This will determine the placement for each layer of siding in the building and must be installed properly.  For more info on installing steel panels, go to: http://www.ehow.com/how_4615109_install-steel-siding.html
